5 Claims. (Cl. 124--45) This invention relates generally to guns and refers more particularly to improvements in pneumatic guns.

One of the objects of this invention is to facilitate loading of single action pneumatic guns by providing means on the gun barrel for removably supporting a shot holding magazine.

Another object of this invention is to provide a magazine in the form of a tube adapted to hold apredetermined number of shot, and capable of being readily attached to the gun in a position enabling the shot to be quickly transferred from the magazine to the breech end of the barrel.

A further feature of this invention is to provide a delivery tube secured to the gun in a position immediately adjacent the shot loading opening in the breech end of the gun barrel and having the entrant end registerable with the delivery end of the magazine to receive shot from the latter.

A still further object of this invention is to provide an arrangement of the above type which does not appreciably add to the weight of the gun and does not interfere with sighting or handling the gun.

The foregoing as well as other objects will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawing, wherein:

Figure 1 is a fragmentary perspective view of a gun having a magazine assembly embodying the features of this invention;

Figure 2 is a longitudinal sectional view through the magazine assembly;

, Figure 3 is a fragmentary plan view partly in section of the breech end of the gun shown in Figure 1;

Figure 4 is a cross sectional view taken on th plane indicated by the line 4-4 of Figure 2; Figure 5 is a cross sectional view taken on the plane indicated by the line 55 of Figure 2; and Figure 6 is a fragmentary longitudinal sec-' tional view of a part of the magazine assembly. It will be understood as this description proceeds that the magazine assembly forming the subject matter of this invention may be ad-,

vantageously used in connection with various different types of single action guns designed to.

fire shot of either the ball or pellet types. For the purpose of illustrating this invention, however, the magazine assembly is shown in connection with a single action pneumatic gun of the general type shown and described in detail in my copending application Serial No. 762,391, filed July 21, 1947, and now abandoned. M

It is not essential. for a complete understand ing of this invention to define the action of the gun, and therefore, this specification will not be complicated by a detailed description of the particular gun illustrated. It will suffice to point out that the gun comprises a stock I0 and a frame II. The frame H in turn comprises a barrel I2, a storage chamber H) for air under pressure and a supplementary storage chamber I l. The storage chamber i3 is in the form of a tube, and is located directly beneath the barrel 12 in the maner clearly shown in Figures 4 and- 5 of the drawings. The supplementary storage chamber I4 is also in the form of a'tube, and is supported directly beneath the storage chamber I3. As indicated in Figure 1 of the drawings, the storage chamber I4 is somewhat shorter than the chamber l3, and communicates with the latter in a manner not shown herein.

The breech end of the barrel I 2 is shown in Figure 3 of the drawing as having an opening l5 through the top wall into which shot either of the ball or pellet type may be inserted. The opening I5 is normally concealed by a sleeve or cap l6 suitably supported on the frame I l at the breech end of the barrel I2 for sliding movement longitudinally of the gun frame. In the actual construction of the gun the cap I6 is connected to the cocking mechanism (not shown) for cocking the gun, and is also connected to a firing pin, also not shown, for propelling the shot to its firing position in the barrel [2 upon forward movement of the. cap IS. The cooking mechanism is released to fire the shot through the barrel l2 by a trigger l1 housed in a trigger guard 18 in accordance with conventional practice.

} The present invention concerns itself more particularly with the means for conveniently and quickly reloading the barrel after each shot, and this is accomplished herein by the provision of a magazine assembly indicated generally in the drawing by a reference character I 9. The magazine assembly I9 comprises a pair of brackets 20 and 2! mounted on the barrel I2 at points spaced from each other longitudinally of the barrel. A tubular housing 22 is welded or otherwise permanently secured to one side of the bracket 20, and is positioned with its axis extending parallel to the axis of the barrel I2. A plunger 23 is supported in the housing 22 for sliding movement and has a stem 24 which projects rearwardly through an opening in the rear end of the housing. The plunger 23 is normally maintained in a position at the rear end of the housing 22 by a coil spring 25located in the housing 22 at the front end of the plunger 23. The rear end of the shown in Figures 1 to 3 inclusive of'the drawing;

The internal diameter of the tube 28 is predetermined to freely slidably'receive shot; such for example, as pellets P. In Figure-eofjthe:

drawing, a plurality of pellets P are shown in position in the tube 28, althoughcitwill'beaunder stood that the tube will accommodate other types of shot. the drawing that a pair of elongated slots 29 are formed: in. diametrically opposite. sides of the tube 281 at the rear: or breechv end of the; latter.

Therear. ends of: the: slots. 29 'aresopen. and. thewidth of the slots issufiicientito' enable the user tQ-graspthe pelletsbetiween: the. thumb and forefinger when it is desired'to. extract a pellet from the-deliveryendof the tube. Accidental removal of the pellets P' from the: rear or delivery end of the tubeZBis-preventedby-means of .a spring clip 30'having; the front endfixed to the'underside of the-tube 2-8 and: having; the rear. end curved upwardly. to: assume a' position in registration with the-rearwardmost pellet P in the tube: 23; The strength of. the. spring 30, is merely sufficient: to hold the pelletsP against removal from the tube under the action1of gravity... and maybe readily overcome by theuser whenitis desired tov extract. apellet from the. delivery end of, the tube. Referring now to Figure 3 of: the drawings, it will be notedthat the: delivery end of the tube 28 is located in relatively close proximity" to the opening E -in. the: breech end of the barrel" l-2-, so'- that a pellet or shot may be: quickly transferred from the delivery end;2'8-- to the-opening l5.

I-he shot or. pellets aresupplied to. the: tube 28- by a" tubular magazine or holder 3h. The front endaof the" tubular magazine 3| is formed with a socket 3-2. adapted to receive the rear end ofv the. stem 2.4- onthe plunger 23, and the? breech, or rear end of the magazine isada-pted-to be sleevedinto the-front end of. the. bushing 21 in the manner. clearly shown in Figure 2 of. the. drawing:

Theconstruction is such that. the rear or deli-v-- between the rear end of. the stem 24. and thefront.

end oi? the tube28, so. that. when the. magazineiis in;its assembled position, the spring 25..is under compression. Thus the spring acts through the magazine forwardly suificiently to disengage the rear end of the magazine from the bushing 21.

During this operation the plunger 23 is moved forwardly in the housing 22 to further compress the spring 25. However, as soon as the rear end of the magazine is released from the bushing 21, thespring'25returns the plunger to its rearwardmost position. The magazine filled with shot is then assembled on the gun by merely engaging the socket 32 on the front end of the magazine witl'i'therear. end of the plunger stem 24 and by 7 inserting the rear end of the magazine into the front end of the bushing 21. The spring 25 is, of

course; compressed by the plunger 23 to enable assemblingthe rear end of the magazine with the bushingZ'I and remains under compression subsequent to.;thez above assembly in order to yield.-

It will also be noted from Figure e erplunger 23. and. cooperates with. the bushing. 21

to hold the magazine 3|.- inassembled. position.

The magazine 3| has an. internal diameter corresponding to the internal diameter. of the tube 28. and. freely slidably retains. a plurality of. shot. The. arrangement is.such.that in the, assembled positionof the magazine 3.! on. the gun the. tube. 2.8. may be. replenished with shot by merely tiltingnthe. muzzle end of the gun upwardly at an angle suflicient to enable shot toslide downwards ly into the tube 28 by the. action of gravity. Whenthe magazine is. exhausted of shot, the latter. may be. readily interchanged with another magazine filled with shot by merely sliding the ably retain the magazine in place.
